RAIL-JOINT.

Speeieation of Letters Patent.

Patented Aug. 18, 1914.

Application filed August 21, 1906. Serial No. 331,527.

To all whom t may concern Be it known that I, HoRATro G. GILLMon, a citizen of the United States, residing at Bath, in the county of Sagadahoc, State of Maine, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification, accompanied by drawings.

This invention relates to rail joints; and

one of its objects is to so form such joints the joint upon the upper and lower surfaces,

f of the base flanges of the rails.

Another object is to provide for securely locking the nuts upon the bolts securing the fish bars .in position. v

Further objects of the invention will hereinafter appear; and to these ends the yinvention consists of a rail joint for carrying out the above objects embodying the features of construction, combination of elements and arrangement of parts havingthe `general mode of operation as hereinafter described and claimed in this specification and shown in the accompanying drawings, in which- Figures l and 2 are, respectively, a transverse sectional vview at the line X X and a side elevation, partly in section, of a joint embodying the invention. Figs. 3 and 4 are, respectively, a transverse section at the line Y Y and a plan view of a joint using a modified form of the clamp bars.

Referring to the drawings: A, represents the meeting ends of the rails.

B represents fish bars of the usual` type, held in position by bolts C fitted with nuts D.

E is a base platev overlapping the rail ends, upon which the rails rest. This base plate has upwardly projecting lugs F which interlock with corresponding notches in the fish bars. f'

l G represents clamp bars or clamps having a longitudinal stiffening flange II.

f lOne of the features of this invention resides in the fact that pressure is exerted by the parts of the joint upon the upper and lower surfaces of the base flanges of the rails in addition to the usual pressure of the fish bars upward under the heads of the rails and downward upon the upper `surfaces of the base flanges. These ends are obtained byr employing the clamps G. After the fish bars have been applied in the usual manner and the nuts well set up on their bolts to draw the fish bars into position; the

bars G are applied with the arms I, which are at an angle to the body of G, engaging with the flange ofthe fish bars while the body of G engages with the bottom of the base plate. The bars G are then driven into position by lateral blows with suitable hammers or mauls and when so driven e'ectually clamp the base flanges of the meeting rail ends between the baseplate and the fish bar flanges. 'Io retain the bars G in position, f their' stiffening flanges I-I are pierced with suitable holes andfbolts II are inserted and nuts set up on them. By setting up the nuts L simultaneously with driving the bars into position, the operation of driving thesek latter' into place is facilitated. The flanges I possess some elasticity so that the nuts may be finally set up sufficiently to spring these flanges. The effect of this is to lock the nuts L against slackening and to prevent slaclening of the clamps even though the nuts L should move somewhat on their bolts. `The arms I of the clamps are so constructed that, when the clamps are in place, one or both of the arms I will come below and in such proximity to a part or all of the nuts D, by which the fish bars B are secured in position, as to prevent these from turning upon their bolts more than a very small amount without coming into contact with I, and so being locked against further slackening. The bolts traversing the rails andthe fish bars secure the rails against all but small movements relative to the fish bars. The lugs F on the base plate engaging with notches in the flanges of the fish bars, lock the fish bars and the base plate. The base plate is also notched to receive-the clamp bars G. The portions of the base plate mentof the rails resisted by the ballasting bars kin position.

material in which the ties are set.

The modified forni of the joint illustrated in Figs. 3 and A differs from that just described in that the stifi'ening flanges 1 project upward instead of downward and are provided with holes to receive the vproj ecting ends of the bolts C used in securing the. fish The nuts L applied to these bolts retain the clamp bars G in posi# tion, the flange 'I of the clamp bars G springing as previously described to exert a locking action upon these nuts. rThe base plate is omitted in.y this modified form of ,the joint and the clamps made longer and provided with horizontally extending flanges N which have spiking apertures through which the spikes M are driven to secure the parts to the ties.

TWhile bolts have been shown for securing the clamp bars G in position, other means, such for example as split pins, etc., might be employed for the purpose.

Obviously some features of this invention may be used without others, and the inven-y tionfmay be embodied in vwidely varying forms. l

Therefore, without limiting the invention to the constructions shown and. described nor enumerating equivalents, I claim and desire to secure by Letters Patent the following: l

l. A rail joint, including, in combination with the rails and fish bars, a base plate and a clamp bai constructed with a base engaging with the base plate, an arm integra-l with said base at an anglethereto engaging withsurfaces of a fish bar above the bases `of the rails and a .longitudinal stiffening web integral with and projecting from the base of said clamp bar, substantially as `described. y

2. A rail joint, including,in combination with the rails, a fish bar, a base plate, and a clamp, constructed with a longitudinal stiffening flange and two jaws to bear upon the base plate beneath and the fish bar above thebases of the rails, substantially Vas described. j i

3. A rail joint, comprising the rails, sh

bars, a'clamp constructedwith a longitudinal stiff'ening web and two jaws to bear upon the base plate underneath and a fishV bar above the basesof the rails, substantially as described.

1l. A rail joint7 including, in combination with the rails and fish bars, a base plate, a

cla-mp constructed with a longitudinal stiffening flange and two jaws constructed to bear upon the base plate underneath and a fish bar above the bases of the rails and means for securing said clamp in position.v

5. A rail joint comprising the rails, fish bars, a-base plate, clamps, at opposite sides of the rails, constructed with longitudinal stiffening webs or flanges and two jaws adapted to bear'uponthe base plate under-l neath and a fish bar above the bases of the rails, and means for securing said clamps in position, for substantially the purposes set forth.

6. A rail joint comprising the rails, fish bars having flanges, a base plate` having upwardly extending lugs, interlocking with the flanges of the fish bars, and suitable spiking apertures, a clamp, constructed to engage with the parts vof the joint, produce a downward pressure upon the upper and an upward pressure upon the lower surfaces of the bases of the rails, and interlock with the base plate, means for securing` the j said clamp in position, and spikes traversing the spiking apertures of the base plate, for substantially the purposes set forth. f

7.y A rail joint, comprising the rails, fish bars, having flanges, a base plate, having up-r wardly extending lugs, interlocking with theflanges of the fishbar, and suitable spiking apertures, a clamp, of substantially imiform section, constructed to engage with the parts of the joint, produce a downward pres-y sure upon the upper and an` upward pressure upon the lower surfaces of the bases of the rails, and interlock with the base plate, means for'securing'thesaid clamp in position, spikes traversing the spiking apertures of the base plate, for substantially the purposes set forth. o
